CAR-AXLE BOX.

lVCi'-EATON forming part of Letters Patent No. 318,879, dated Ivl'ay 26,1885.

Application tiled February 12, 1835. (No model.)

To @ZZ whom, it may concern.:

Be it known that we, GEORGE E. DE GRANGE and firman G. GREEN, citizensofthe United States, residing` at New Orleans, Louisiana, have inventednew and useful Improvements in Car-Axle Boxes, of which the following isa specication.

Ourinvention relates to that class of caraxle boxesin which the journalof the axle revolves in a chamber containing the lubricant and asuitablevehicle-such as tow or cotton or other medium-#for feeding thelubricantto the j ournai.

The object of the invention is to provide simple and effective means forexcluding dust and grit from the interior of the box, therebyrpreserving the oil or lubricant in a free and clear condition, so thatthere will be no appreciable wear of the journal and the brass orbearing. The invention also has for its object to prevent the loss ofoil at the front of the box where, asin ordinary boxes heretoforedevised, the oil is liable to escape through the joints between thecover and the box.

To these ends the invention consists in fitting a cup-shaped annularflange on the axle of the wheel and providing the rear end of theaxle-box with a boss carrying a collar, which fits into or is inelosedby the annular flange on the axle. Said collarbears a packing-ring uponits outer face,which rests against the bottom ofthe cup-shaped annularflange, so that the parts thus 'fitted will efectually prevent theentrance of dust or grit into the oil or journal chamber.

The invention also consists inlocating a vertical division-plate at thefrontof the oil-chama ber of the axle-box, said plate extending fromnear the iloor of the chamber up to the under side of the journal of theaxle, and being arranged at the inlet opening or mouth of the axle-box.The object of said plate is to arrest the outward low of the oil causedby jolts or concussions when the car is turning curves, or

from other causes, thereby preventing the oil' from being thrown againstthe axle-box cover and leaking` out through the joints. Said stopplatedoes not extend to the bottom of the oilchamber, and hence the lattercan be replenished with oil by causing the same to flow under the plate.

In the drawings, Figure 1 is a longitudinal section of a car-axle boxembodying our ilu- Vprovenients. Fig. 2is a detail view ofthewheel,

axle, and cup-shaped tlange on said axle.l Fig. 8 is a rear view of theaxle-box, representing` the collar and packing-ring applied thereto.

The referenceuiumeral l designates an axlebox, which is made ofcast-iron in the form and manner usually employed lfor this purpose, andis fitted in an appropriate hanger or pedestal, so as to slide up anddown as the customary pressure-springsV contract or expand. A bearing orbox, 2, of brass or other composition metal,ts the journal 3 of the axlefl, and is provided on its back with a transverse groove to engage witha rib, 5, on the under surface of the top ofthe box, so as to preventsaid bearing from moving in the direction or the length of the axle. Inthe front of the box is an openin g, which is closed by a lid or cover,6, that can be removed or lifted to renew the oil or lubricant and lhecotton waste, tow, or other medium for holding the oil and feeding it tothe journal.

As sh'own in the drawings, the upper edge of the cover engages with arecess, 8, formed near the top of the box l, and its lower edge has auapertured lug, 9, through which is passed a pin or screw, 10, thatenters a seat or socket, 11, on the box and holds the cover in position.

At the sides of the opening or mouth ofthe box are formed guideways forthe reception of the detachable plate 12, which, when in position, bearsagainst the front end of the axlejournal, so as to preventthelongitudinal movement thereof.

All the parts above designated are similar to those used in axle-boxesheretofore devised, and form no part of our invention.

At the freut of the oil or lubricant chamber and a short distance fromthe solid front wall, 13, disposed below the mouth or inlet opening, islocated a transverse plate, 14, which rises from near the bottoni of theoil-chamber to a. point immediately below the Linder side of the journalof the axle. Said plate 14 is generally inclined in an inward directionfrom the front of the axle-box, and a space or filling chamber, 20, isthus left between the front wall, 13, and said plate 14. Then oil ispoured into said space 20, it will flow under the plate 14: into thelubricatingchainber, as will readily be ap- IOC flange can form anintegral part of the car- Wheel16 by being east on the inner facethereof. On the rear face or Wall of the axle-box is formed a hub orboss, 17, which has an outer collar or ring-plate, 18, made of such sizeas to fit into the cup-shaped angeand plate on the axle, but beingsmaller than the seat-space in said eup'sh'aped flange, so that theylatter can vrevolve around the ring-p-late 18 Without frictio-n againstits periphery. The inner face of the ring plate or collar 18 carries a-nelastic or other suitable packing-disk, 19, which bears against thebottom ofthe cup-shaped fla-nge and prevents access of dirt and grit tothe axle passing through the packing-disk 19, plate 18, and hub 17.

By providing an axle-box with our attachments-abovefully setforth weefteetually guard against the leaking ont of the oil through the frontand rear of the box, and also prevent the entrance of dirt and grit intothe interior of the box, thus preserving the bearings and journalsintact for a vastly longer period than is the case with the axle-boxesheretofore known.

What we claim ism 1. The combination ofthe axle-box provided with thehub or boss 17 formed integral with the annular metallic disk 18, withthe flexible packing-disk 19, attached directly to the inner face of themetallic disk, the axle, the wheel, and the cup-shaped annular ange 15,substantially as described.

2. The car-axle box provided with the transverse division-plate 14,having its upper and lower horizontal edges terminated, res-peetively,'at a distance from the car-axle and the bottom wall of the box,substantially as and for the purpose described.

In testimony whereof Weafix oursignatnres in presence of two Witnesses.
